Abstract

The lifetime of high voltage equipment is very dependent on the condition of insulation, poor insulation means the life span of high voltage equipment is getting shorter. Partial Discharge is one of the causes of deterioration of high voltage equipment insulation. The ability to know the phenomenon of partial discharge in equipment becomes very important and adds value to the maintenance of high voltage equipment. Many explanations regarding partial discharge, partial discharge is the lack of uniformity of the electric field in the isolation or dielectric media which will result in the phenomenon of Partial Discharge where this will lead to the failure of the isolation media. Partial Discharge that occurs continuously can cause damage (breakdown) on a high voltage equipment. Therefore, before a high voltage device is used, Partial Discharge detection is necessary. Partial Discharge Detection can use the Partial Discharge measurement circuit. In testing partial discharges can be tested using a sensor with various circuits including High Frequency Current Transformers (HFCT) so that this research will discuss one part of the Partial Discharge measurement circuit, the HFCT detector. Hopefully, the HFCT detector can be further developed and can be used for better partial discharge detection.

Abstract

Partial Discharge is a localized electric discharge that only partially connects insulation between conductors, and can appear parallel or not to the conductor. Partial discharge (PD) has long been recognized as an important indication of the state of isolation in high voltage equipment. By measuring PD, a diagnosis of the degree of degradation or deterioration in the isolation conditions of a high voltage device can be determined. Partial Discharge that occurs continuously can cause damage (breakdown) on a high voltage equipment. Therefore, before a high voltage device is used, Partial Discharge detection is necessary. Partial Discharge Detection can use the Partial Discharge measurement circuit. In this study, one part of the Partial Discharge measurement series will be discussed, namely the RC detector. Hopefully, RC detector can be further developed and can be used for more accurate partial discharge detection.

Abstract

Petir merupakan kejadian alam yang disebabkan oleh terjadinya loncatan muatan listrik antara awan dengan bumi. Petir menimbulkan adanya rambatan gelombang dengan amplitudo transien arus dan tegangan tinggi. Tegangan dan arus lebih yang ditimbulkan oleh petir selain dapat mengancam keselamatan jiwa manusia, juga dapat mengganggu peralatan dan sistem tenaga listrik. Gangguan akibat petir dapat timbul dari sambaran petir langsung (direct strike) dan tidak langsung (indirect strike). Oleh karena itu diperlukan suatu sistem proteksi yang mengamankan saluran transmisi, peralatan, atau manusia dari gangguan dan sambaran petir. Sambaran petir yang merusak isolator terdiri dari dari 2 sumber, yang pertama; yakni sambaran langsung kekawat tanah atau menara. Arus petir akan mengalir ketanah melalui menara dan kembali keatas dengan tegangan yang tinggi dan menyebakan rusak dan pecahnya isolator, fenomena ini disebut Back Flashover (BSF). Yang kedua yakni sambaran langsung ke kawat Fasa, arus petir akan mengalir sepanjang kawat fasa sebagai gelombang berjalan ke isolator dan merusak isolator, ini disebut Shielding Failures (SF).Fenomena-fenomena tersebut bisa dianalisa dengan simulasi menggunakan Elektromagnetik Transient Program.
